Cooperative parents, rejoice. A new study from Georgia State University found couples that shared child-care responsibilities reported more sexual happiness than those who did not.

As reported by Market Watch, the study used data from nearly 500 heterosexual couples who were raising one or more children together.   Most previous research have found that so-called “traditional arrangements,” when the woman take son the majority of the child-care and household responsibilities, were most likely to indicate a sexually happy relationship. However, this new study found exactly the opposite.

Relationships in which the woman did most or all of the child-care were discovered to be “highly problematic” to a healthy sexual dynamic. Instead, splitting child-care duties fairly evenly led to couples reporting higher quality relationships and greater intimacy.

Daniel L. Carlson, associate professor of sociology at Georgia State University and one of the study’s co-authors, explained the results by hoping that as a population, “we embrace egalitarianism…traditional arrangements are increasingly something couples want less.” Despite this trend, the Pew Research Center reports that women still spend twice as much time as men on child-are and house-hold duties.

One other interesting finding was that men who spent more time on child-care than their female partner reported significantly lower satisfaction with their intimacy and sexual relationships.   However, these lower findings did not carry over to the women’s point of view, as they reported around normal levels of satisfaction.

Time to draw up a responsibility chart.
